LINE + Claude integration
Connect LINE to Claude
ConnectChats brings your LINE chats into Claude. Ask Claude to catch you up, find any message and draft replies. Nothing gets sent until you approve it.
Free to start. No app to install. Every send needs your OK.
What Claude can do with your LINE
ConnectChats gives Claude a small set of tools. Claude calls them when you ask about your LINE chats, and only for the chats you share.
-
Catch you up
Ask what you missed and Claude reads your unread LINE chats, then gives you the short version: who needs an answer, what was decided, what can wait.
get_messages_to_summarize -
Find any message
The address someone sent last month, the price a client agreed to, the link from a group chat. Claude searches your LINE history and quotes the message.
search_messages -
Draft replies
Claude writes the reply in your tone, in the chat's language, with the context of the whole thread. You read it, edit it, and send it.
draft_reply -
Send with your OK
When you approve a draft, ConnectChats sends it from your own LINE account and confirms delivery. Auto-send only runs in chats where you switch it on.

How LINE and Claude work together
ConnectChats signs in to your LINE account the way LINE for PC does, and your AI app sees the chats and groups you share. Your phone stays your main device.
-
LINE in ConnectChats
One to one chats and groups are supported. LINE official accounts you follow appear as chats too. Stickers show up as short text descriptions, along with photos, videos and voice messages. Each linked chat starts with its last 200 messages, then every new message arrives as it is sent. LINE allows one PC sign-in at a time, so linking ConnectChats may sign out LINE on your computer.

ConnectChats in Claude
Claude supports remote MCP servers as custom connectors. Add ConnectChats once, sign in with your passkey, and switch it on in any conversation where you want Claude to see your chats. Custom connectors work on every Claude plan, including Free, which allows one custom connector. On Team and Enterprise plans, members cannot add connectors themselves. An owner adds ConnectChats in Organization settings, then each member connects their own account. Add the connector on the web or desktop. It then works in the Claude iPhone and Android apps too. Claude connects from Anthropic's cloud, not from your computer, so nothing needs to stay running on your side.
Your LINE stays under your control
-
You pick the chats
Claude only sees the LINE chats you share. Unshare a chat and it disappears from every AI app at once.
-
Drafts by default
Claude prepares replies. You approve each one before it reaches LINE, unless you turn on auto-send for that chat.
-
Stored messages are encrypted
Stored messages are encrypted with a key that only your passkey can unlock. We never train models on your messages.
Questions
Can Claude read my LINE messages?
Yes, once you link LINE in ConnectChats and add ConnectChats to Claude. Claude reads only the chats you share, and only when you ask it something that needs them.
Can Claude send LINE messages for me?
Claude can draft a reply and send it after you approve it. Messages go out from your own LINE account. You can allow automatic sending for specific chats, and it stays off everywhere else.
Is the LINE to Claude integration free?
Yes. The free plan links two chat apps and works in every supported AI app, with no limit on what you ask. No card needed.
Do I need to install anything?
No. You add ConnectChats inside Claude and link LINE from your browser. There is no app to download and nothing runs on your computer.
Does it work with other AI apps too?
Yes. The same ConnectChats account works in ChatGPT, Claude, Grok, Manus, Muse and any AI app that supports remote MCP servers. Link LINE once and use it everywhere.
Does it understand Japanese or Thai chats?
Yes. Your AI app reads messages in their original language and can summarize them or draft replies in that language, or translate them for you.
Do I need to register an email in LINE?
Yes, because LINE uses your email and password for sign-ins on other devices. You can add one in LINE under Settings, Account.
Does it work on the free Claude plan?
Yes. Claude's free plan allows one custom connector, which is enough for ConnectChats.
Can I use ConnectChats in the Claude mobile app?
Yes. Add the connector on claude.ai or in the desktop app, and it is available in the iPhone and Android apps on the same account.
Is this the same as using ConnectChats in Claude Code?
It is the same ConnectChats account, but Claude Code is set up separately with one terminal command. Your linked chats and sharing choices carry over.
